20080211756 | Driving method of liquid crystal display apparatus, driving apparatus of liquid crystal display apparatus, and program thereof - A liquid crystal display apparatus includes a plurality of areas in which response speeds greatly different from each other coexist in a pixel. A first replacement process section replaces the image data of the desired target frame with a first gradation, when a gradation transition from a current frame to a desired target frame corresponds to the above gradation transition. A second replacement process section replaces the image data of the current frame with a second value. The first value is set to a value causing the pixel to respond at a relatively higher speed without the occurrence of the excessive brightness. Without avoiding the deterioration of the image, it is possible to drive a liquid crystal display apparatus including areas whose response speeds are different from each other coexist in the pixel, such as a liquid crystal display apparatus of vertically aligned mode and normally black mode. | 09-04-2008 |

20110063529 | Display apparatus driving method, display apparatus driving device, program therefor, recording medium storing program, and display apparatus - A control section divides a display screen into small regions, evaluates the relative brightness of each of the small regions in accordance with color data to be inputted as color data by which each pixel is displayed, and determines whether or not the display screen has a first small region that is brighter than the other small regions by a predetermined degree. Furthermore, the control section causes a first generating means to generate gradation data for use in the first small region, and causes a second generating means to generate gradation data for use in the other small regions. Even if the second generating section receives the same color data as the first generating section does, the second generating section limits the luminance of a W sub-pixel as compared to the first generating section. With this, the first small region can be displayed more strikingly brightly, so that a clearer, more realistic, and more appealing image can be displayed. This makes it possible to realize a display apparatus capable of displaying a clearer, more realistic, and more appealing image. | 03-17-2011 |
20110134154 | Liquid crystal display device, image display device, illumination device and emitter used therefor, driving method of liquid crystal display device, driving method of illumination device, and driving method of emitter - The cold cathode tube for illuminating pixels with light which is in accordance with an output signal has luminance which gradually increases at a rise and gradually decreases at a fall per one frame time. The cold cathode tube contains a fluorescent material of only one of three primary colors of light, and has a certain OFF period or dimming period per one frame time. Between a diffusing plate and a reflecting plate are provided partition walls for parting emitting areas, so that the illumination light of one cold cathode tube does not reach the display elements to be illuminated by the other cold cathode tubes. The emission of each display element is changed per one frame time between a normal ON state and a dim state. The cold cathode tube has two or more OFF periods within one frame time, and luminance of the cold cathode tube is changed per one frame period. As a result, it is possible to suppress shortening of life of emitters in an illuminating section, and to relieve lowering of luminance of the emitters, and also to obtain a desirable display quality even in a fast-moving image. | 06-09-2011 |

20110194039 | Liquid crystal display apparatus having an input gradation set to have relationship along a gamma curve - In a liquid crystal display apparatus realizing a dual view display by bonding a liquid crystal panel and a parallax barrier, the parallax barrier separates display images by treating three pixels including R, G, and B pixels as one unit (one picture element). At this time, luminance variation due to crosstalk concentrates on a right-end pixel among the three pixels constituting the one picture element (in a case where each pixel receives data from a source line immediately on the left of the pixel). Accordingly, the right-end pixel is arranged to be a B pixel that has a low correlation with luminance information and in which influence of crosstalk is hard to be viewed. Further, an applied voltage to be supplied to the display pixel of the B (blue) color and an input gradation are set to have a relationship along a γ curve that makes luminance variation difficult to occur in a low luminance area. | 08-11-2011 |

The provision of the light diffusion layers enables reducing moire pattern occurrences which would otherwise markedly increase when two liquid crystal panels are stacked. As a result, the liquid crystal display has high display quality. | 10-27-2011 |
